Thermostatic mixing valves

摘要

A thermostatic mixing valve 201 for hot and cold water has two-stage inlet chambers 219,221 and 220,222 for the hot and cold water flows respectively. The inlet chambers 219,221 and 220,222 distribute the flows uniformly with respect to porting for admitting the flows to the mixing chamber 226 to reduce asymmetric flow patterns and promote thorough mixing of the flows within the mixing chamber 226.
